Beacon Power, the project contractor, says it built the world's largest energy storage in Stephentown, N.Y.. They'll even host a ceremony at the official launch date, July 12.

Taking into account the destination of the projected batteries, to act like a buffer for storing renewable electricity, low voltages are enough, so making the technology cheaper by using a water-based electrolyte wasn't hard to think of.
